PRESS FOR FINISHING LEATHER LOOPS.

Application filed August 17, 1911. Serial No. 644,660.

. State of Connecticut, have invented a new and useful Improvement in Presses for Finishing Leather Loops, of which the following is a specification.

'This invention relates to a machine which is more particularly designed. for pressing and finishing leather loops, such as are used on harness parts for the purpose ofretaining the end of straps that are buckled and tucked through the loops, although, of course, the machine may be used for pressing other articles. f r Y The object of the invention is to provide a very simple, cheap and powerful press which can be quickly operated for pressing harness and similar loops into angular shape, and, at the same time if desired, embossing lines or other ornamentation upon the top and side surfaces of such loops;

Figure 1 'of'the. accompanying drawings shows a side elevation ofa press which embodies the invention. Fig.2 shows a front view of the same. Fig. 3 shows a horizontal section looking down onthe plane indicated by the-dotted line 33 on Fig. 1.

Fig. 4 shows a transverse section on the plane indicated by the dotted line 44 on Fig. 3. Fig. 5 is a viewlooking up at the three dies, which may be used in this press, forfinishing a leather harness loop, the dies being on larger scale than shown in the other views. Fig. 6 shows a side View of the dies. Fig. 7 shows a section of these dies pressing a loop. Fig. 8 -shows the end of a strap provided with such a tuck loop as would be finished by the dies hereillustrated, when subjected to the action of the press which forms the subject of this invention.

The press illustrated has a frame preferably comprising a table-plate 1, having astandard 2 extending upward from the rear edge of the plate and a head 3 at the top ofthe standard. Movable up and down the front, face near the top of the standard is a block 4c. This block carries a roll 5 which is engaged by the periphery of the cam 6 that is pivoted in the frame head and is provided with a handle 7. Adjustably held in a slot in the front of the block, by the ranged to hold up the long arm of the lever which is engaged by the roll carried by the bars that are connected'to the top die-block. One end of this spring is connected with the lever, as shown, and the other end maybe connected with the supporting bench or any other convenient part. The lever is mounted on a pivot that is carried by bearings19 which are movable horizontally in slots in held by set screws 21. The end of the short arm of the lever engages the front edge of a block 22, that is mounted on a T-shaped slide 23' which is arranged to move back and forth in a suitably shaped guide-way in the bed. Springs 24 are arranged to hold this horizontally movable die-block against the end of the lever. The front die 25 is clamped to the face of this blockby plates 26 which are opened for releasing the die and closed for holding the die by turning the screw 27 that is provided with right and left threads. In the front of the standard is the stationary die-block 28. This block 'is adjustable toward and from the front by the screw 29. The back die 30 is clamped to the face of this block by plates 31 which are opened and closed for releasing and left threaded screw. 32.

The top or verticallymovable die is usually provided withv 'a' bottom surface so shapedthat' it will emboss the top surface of the loop with the desired pattern. The opposing faces of the backor stationary die screw Sand nut 9 is a die holder 10. They the bed 20. These bearings are adjustably holding the die by turning the right and and the front or horizontally-movable die are similarly shaped so as to emboss the same design on the sides of the loop. When the dies are cut to emboss a continuous pattern on the top and the sides of a loop, the side surfaces of the top die are shaped to a fit the faces of the back and front dies so sharp right-angular corners on the loop.

thatthe dies will close togetherand form If aloop, such as the tuck-loop 33 on the strap 34, shown in Fig. 8, is to be pressed and given square corners and provided with four grooves 35 that are continuous on its top surface and two sides, the bottom face of the top vertically movable die must be shaped to emboss these grooves and the opposing faces of the back stationary die and the front horizontally movable die are similarly shaped to impress a continuation of these grooves in the sides of the loop: In order to have the dies come together and i give the loop square corners, the edges of the top die must be shaped so that they will fit the faces of the back and front dies. WVhen the machine described is provided with such dies, the loop is slipped upon a mandrel 36 and placed upon a bed-block 37 between the dies. The cam handle is then drawn forward. This causes the top die to descend in front of the back die. The

downward movement of the top die, through the bars and lever, moves the front die horizontally so that the loop will be powerfully pressedinto rectangular form with square corners by the three dies, as shown in Fig. 7. a The faces of the dies may be left plane if it is desired to simply'square the loop with- Gopies of this patent may be obtained for out-embossing anylines or pattern on the top and sides. The loops are not only squared, that is, made rectangular by the action of this press, but the stitched joint of i the leather ends, which are brought together to'formthe loop, -are squeezed and flattened so that the loop can be neatly stitched between the layers of a strap, if it is not thus theframe and connected with the horizon- 1 tally movable die-block for moving the same, a die-block movable vertically on the frame, a cam for depressing the vertically movable die-block, and means connected with the vertically movable die-block and engaging the lever whereby the depression of said die-block causes the lever to force the horizontally movable die-block rearwardly toward the stationary die-block.

2. A press having a frame, 'a die-block vertically movable on the frame, a cam for depressing the vertically movable die-block, a die-block held stationary on the frame, a die-block movable horizontally on the frame toward and from the stationary die-block, a lever for forcing the horizontally movable die-block toward the stationary die-block, bars connected with the vertically movable die-block and arranged to cause said lever to move the horizontally movable die-block, and a spring arranged to lift said lever and cause the horizontally movable die-block to move away from the stationary die-block and the vertically movable die-block to be lifted when the cam is turned up.

3. A press having a frame, a die-block movable vertically on the frame, a die adjustably secured to said block, a roll carried by said block, a cam mounted on the frame and engaging said roll, a handle for turning said cam and causing it to depress the vertically movable block, a die-block adjustable horizontally on the frame, a stationary die carried thereby, a die-block movable horizontally on the frame toward and from the stationary die, a die carried by the horizontally movable die-block, a lever engaging said horizontally movable block, said lever being adjustably mounted on the frame, bars connected with the vertically movable dieblock, a roll carried by said bars and engaging an arm of said lever, and a spring for holding said arm of the lever in engagement with the roll carried by the bars.
